Swaps Chapter 26 Financial Institutions Management, 3/e By Anthony Saunders Irwin/McGraw-Hill 1 Introduction Market for swaps has grown enormously Serious regulatory concerns regarding credit risk exposures • Motivated BIS risk-based capital reforms • Growth in exotic swaps such as inverse floater generated controversy (e.g., Orange County, CA). Generic swaps in order of quantitative importance: interest rate, currency, commodity. Irwin/McGraw-Hill 2 Interest Rate Swaps Interest rate swap as succession of forwards. • Swap buyer agrees to pay fixed-rate • Swap seller agrees to pay floating-rate. Purpose of swap • Allows FIs to economically convert variablerate instruments into fixed-rate (or vice versa) in order to better match assets and liabilities. Irwin/McGraw-Hill 3 Interest Rate Swap Example • Consider money center bank that has raised $100 million by issuing 4-year notes with 10% fixed coupons. On asset side: C&I loans linked to LIBOR. Duration gap is negative. DA - kDL < 0 • Second party is savings bank with $100 million in fixed-rate mortgages of long duration funded with CDs having duration of 1 year. DA - kDL > 0 Irwin/McGraw-Hill 4 Example (continued) • Savings bank can reduce duration gap by buying a swap (taking fixed-payment side). • Notional value of the swap is $100 million. • Maturity is 4 years with 10% fixed-payments. • Suppose that LIBOR currently equals 8% and bank agrees to pay LIBOR + 2%. Irwin/McGraw-Hill 5 Realized Cash Flows on Swap Suppose realized rates are as follows End of Year LIBOR 1 9% 2 9% 3 7% 4 6% Irwin/McGraw-Hill 6 Swap Payments End of Year 1 2 3 4 Total LIBOR + 2% 11% 11 9 8 MCB Payment $11 11 9 8 39 Savings Bank $10 10 10 10 40 Net +1 +1 -1 -2 -1 Irwin/McGraw-Hill 7 Off-market Swaps Swaps can be molded to suit needs • Special interest terms • Varying notional value » Increasing or decreasing over life of swap. • Structured-note inverse floater » Example: Government agency issues note with coupon equal to 7 percent minus LIBOR and converts it into a LIBOR liability through a swap. Irwin/McGraw-Hill 8 Macrohedging with Swaps Assume a thrift has positive gap such that DE = -(DA - kDL)A [DR/(1+R)] >0 if rates rise. Suppose choose to hedge with 10-year swaps. Fixedrate payments are equivalent to payments on a 10year T-bond. Floating-rate payments repriced to LIBOR every year. Changes in swap value DS, depend on duration difference (D10 - D1). DS = -(DFixed - DFloat) × NS × [DR/(1+R)] Irwin/McGraw-Hill 9 Macrohedging (continued) Optimal notional value requires DS = DE -(DFixed - DFloat) × NS × [DR/(1+R)] = -(DA - kDL) × A × [DR/(1+R)] NS = [(DA - kDL) × A]/(DFixed - DFloat) Irwin/McGraw-Hill 10 Pricing an Interest Rate Swap Example: • Assume 4-year swap with fixed payments at end of year. • We derive expected one-year rates from the yield curve treating the individual payments as separate zero-coupon bonds and iterating forward. Irwin/McGraw-Hill 11 Currency Swaps Fixed-Fixed • Example: U.S. bank with fixed-rate assets denominated in dollars, partly financed with £50 million in 4-year 10 percent (fixed) notes. By comparison, U.K. bank has assets partly funded by $100 million 4-year 10 percent notes. • Solution: Enter into currency swap. Fixed-Floating currency swaps. Irwin/McGraw-Hill 12 Credit Swaps Credit swaps designed to hedge credit risk. Total return swap Pure credit swap • Interest-rate sensitive element stripped out leaving only the credit risk. Irwin/McGraw-Hill 13 Credit Risk Concerns Credit risk concerns partly mitigated by netting of swap payments. Netting by novation • When there are many contracts between parties. Payment flows are interest and not principal. Standby letters of credit may be required. Irwin/McGraw-Hill 14
